Postural control of human body is a complex process involving visual , vestibular, somatosensory system and their central processing , add the vestibular system through its multiple connection coordinates movements of the head with movement of the eyes (to maintain clear vision ), trunk , and limbs (to maintain cephalic and postural stability ) via vestibulo-ocular and vestibulo-spinal reflexes respectively Global postural control shows alterations with aging increasing the chance of falls in the population aged 60 years or older, In older adults, poor postural balance can indicate an impaired ability to recover from small postural perturbations and be predictive of future falls
